Tangs are notably one of the most desired species of fish due to their bold presence, active demeanor, and their need to always be front and center.  There are many varieties of Tangs and they can be kept together with respect to the size of their environment.  They are a peaceful community fish and will thrive in most conditions including a coral reef system or a live rock only system.  Tangs are omnivores and constantly pick at algae and just about any other prepared foods such as meaty seafoods, flakes and pellets.
